1 Claim. (Cl. 126-93) This invention relates to a liquified gas burningtobacco curer.

An object of the invention is to provide a tobacco curer of thischaracter, which is easy to operate, safe to use and since only vaporsare burnt at the curer, no liquid reaches the burner, thus making theburners instantly adjustable as to the heat produced. With anon-varyingflame, higher temperatures are produced in the barn, making a moreeflicient operation of curing the tobacco.

With the above and other objects and advan" tages in view, the inventionconsists of the novel details of construction, arrangement andcombination of parts more fully hereinafter described, claimed andillustrated in the accompanying drawings in which:

Figure 1 is a side elevational view of an embodiment of the invention;

Figure 2 is an end elevational view;

Figure 3 is a vertical sectional view on the line 3-4! of the Figure 1;

Figure 4 is a longitudinal sectional view of Figure 1;

Figure 5 is a cross-sectional view on the line 5--5 of Figure 4;

Figure 6 is a sectional view of the control valve in half open positionand Figure 7 is a sectional view of the control valve in. full openposition.

Referring more in detail to the drawings, the tobacco curer embodyingthe invention is designated generally by the reference numeral 50, andcomprises the end pieces H and i2 respectively, which are bent in asubstantially U-shaped form to provide oppositely disposed side flangesl3 and I3 on end ll, and I4 and it on end 52. The forward edges offlanges l3 and it are provided with outwardly extending right angularflanges l5 and I5 while the forward edge of flanges Hi and it areprovided with similar flanges l5 and it. The upper and lower ends of theflanges E3 and I3 are provided with outwardly extending right angularflanges El and ii, while the upper and lower ends of flanges M and M areprovided with similar flanges i3 and i8, and the upper and lower ends ofthe end pieces I! and 82 are provided with outwardly extending rightangular flanges l9 and 59' re spectively.

The upper ends of the end pieces have secured thereto, on the innersides of the flanges it and I3, and i l and it, by welding or the like,the side plates 28 and 2!! respectively, and these plates havelongitudinal inwardly extending right angular flanges 2! and 2!respectively, while at the lower ends, the end pieces have thedownwardly curved baffle plate or windshield 22 secured thereto by meansof the upstanding flanges 23 and 23 respectively. Extendinglongitudinally of the bafiie plate 22, along the medial line thereof, isthe elongated slot 2 to furnish air to the tubular burner 25 which iscapped at each end by caps 26 and provided with a plurality of burnerapertures 2i. The burner 25 is supported longitudinally of the curer bymeans of brackets 28 and 28 respectively, which are provided with endflanges 29 and 29' respectively, which are secured by welding or thelike to the side flanges it and i3 and M and M.

Interpos'ed in the center of the burner 25 is a control valve 30 whichis connected by a pipe 3! to a fuel supply, not shown. The valve 343 isprovided with ports 32, 33 and 34 respectively, so that, as shown inFigure 6, port 33 will communicate with one-half of the burner 25, andwith the supply pipe 3!, so that only one-half of the burner is in use.In Figure 7, with ports 32 and 3 S communicating with the burner, andport 33 with pipe 3!, the entire burner is in use. The reverse of Figure6 is also apparent since if port 34 is in communication with pipe 3!,port 33 will be in communication with the opposite half of the burner25.

A heat spreader 35, which is substantially formed and shaped as theconventional peaked roof, is provided with vertical depending arms 36,which are provided in pairs at each end of the curer so that they can besecured to the end pieces H and !2 by fasteners 3?, and the heatspreader can be made adjustable as desired by providing a plurality ofopenings to receive the fasteners 31!.

Secured to the inner surface of the heat spreader 35 is a substantiallytriangular shaped hafiie providing a partial de d air s ace 39 betweenthe spreader and the bafile, which prevents the discoloration of thetobacco during the curing thereof. Longitudinal cutouts Mi along thelongitudinal edges of the baffle provide the feet H whereby the baffleis secured by welding to the spreader 35 below the inturned upperflanged ends d2 of the arms 35. The cutouts intermediate of the feet llform a slight air space which permits a slight circulation of air intothe space 39. Thus there is enough air seeping into the space 39 toreduce the temperature of the heat spreader sufficiently to prevent anexcess of heat directly over the heating unit. An excess temperaturewould cause a setting of 3 the green color in the tips of the tobaccoleaves hanging over the unit before the curing process has progressedfar enough for the tobacco to reach the desired color.

The curer is made of sheet metal throughout,

'which may be rust-proofed or galvanized, and

any number of these units may be used in the barn as desired.

There has thus been provided a tobacco curer which, it is believed, willaccomplish the objects of the invention, and it is believed that fromthe foregoing description, the construction and operation of theinvention will be apparent to those skilled in the art.

It is also to be understood that changes in the minor details ofconstruction, arrangement and combination of parts may be resorted to,

provided they fall within the spirit of the in- 4 header, a three-wayvalve positioned in the center of the said burner header and having afuel supply pipe extended therefrom, a baffle carried by the extendedends of the end walls spaced below the header and extended upwardly froma point below the header to the said extensions of the end wall, saidbaflie having a longitudinally disposed opening therein positioned belowthe header, 2. superimposed hood triangular shaped in cross section andhaving inclined side and end walls spaced above the upper end of thecasing, depending arms positioned in the ends of the hood and extendeddownwardly into the casing supporting the hood above the casing, and aninner bafiie positioned midway of the height of the hood extended fromwall to wall of the hood providing a partial dead air space within thehood.
